Hello Leo; I don't have a Saito 72, but I have used the Dubro vibe mount on a Saito 80, 2 actually, a Saito 65, 91,100,45,50 and 56, Oh and a 120 in my Spacewalker. I think the vibration reduction is responsible for my planes lasting so long, plus the fact that I haven
't had a radio glitch forever, but that's good Airtronics radios for you. I currently have one Saito 80, a45S, and a 150 hard mounted. That works too. I would say that if you have the extra room that the mnount requires, use it for the best installation. However, having said that, there are places where you just cannot make the vibe mount fit. The Sig kadet serior will have enough room for the dubre vibration reducing mount.
